DESCRIPTION OF PREFERRED EMBODIMENTS
Referring now to FIG. 1 of the accompanying drawings a six-way connector in
accordance with the present invention comprises a lower horizontal plate 1
and an upper horizontal plate 2 located at a position above the lower
plate 1. The plates 1 and 2 lie in parallel planes. The plates 1 and 2 are
maintained in a spaced apart condition by a cruciform vertical web 3
located between the plates 1 and 2, and by four vertical face plates only
three of which 4, 5, 6 are illustrated in FIG. 1. The fourth face plate
corresponds to the visible plate 5. The described structure is
symmetrical.
It is to be observed that the lower horizontal plate 1 has a greater width
and a greater length than the upper horizontal plate 2.
The upper plate 2 is of generally rectangular form and is provided with a
central aperture 6. Located towards each end of the plate is a further
oval aperture 7 located on the central axis of the plate. The end of the
aperture 7 towards the central aperture 6 is associated with two generally
radially disposed elongate apertures 8, which are located adjacent, but
spaced from, the aperture 7. Two further pairs of round apertures 9 are
provided adjacent but spaced from the ends of the upper plate 2.
The lower horizontal plate 1 has a similar pattern of apertures to that
described with reference to the upper plate 2, but, because it is longer
and wider than the upper plate 2, the lower plate 1 is of a generally
lozenge shape.
The vertical plates 4, 5 and 6 each extend vertically between a free edge
of the upper plate 2 and the lower plate 1. Because the lower plate 1 is
larger than the upper plate 2, each vertical plate 4, 5, 6 abuts the lower
plate 1 at a position spaced inwardly from the free edge of the lower
plate 1. Thus platform areas 10, 11, 12 are created defined by that part
of the lower plate 1 adjacent the lower edge of each of the vertical
plates 4, 5, 6. Each platform region is bounded by two upstanding vertical
webs 13 located adjacent the base of the vertical plates 4, 5 and 6 and
extending perpendicularly thereto. The webs 13 are aligned with the
vertical edges of the plates 4, 5 and 6.
Each vertical plate 4, 5, 6 is provided with a central circular aperture 14
which is surrounded by four generally targentially inclined oval apertures
15.
Referring now to FIG. 2 a soldier 16, which is a well-known item per se can
be brought into engagement with the described six-way connector to extend
horizontally therefrom. It can be seen that the end of the soldier that is
to be engaged with the six-way connector may be rested upon the platform
10. When the soldier rests on the platform 10 apertures 17 formed in the
end plate of the soldier are aligned with the oval apertures 15 formed in
the vertical plate 4 and appropriate nuts and bolts may be used to secure
the soldier to the end plate 4. There are four apertures 17. They do not,
however, lie on the corners of a notional square, but instead lie on the
corners of a notional rectangle. It is to be appreciated that whilst the
soldier 16 has been shown being brought into engagement with the six-way
connector in one orientation, the soldier may be rotated through
90.degree. about its horizontal axis and may be still brought into
engagement with the six-way connector. In this condition the end of the
soldier will rest on top of the webs 13, and the arrangement is such that
the apertures 17 are still being aligned with the oval apertures 15. It is
for this reason that the oval apertures 15 are oval and have an axial
extent, since the apertures 17 formed in the end plate of the soldier are
not totally symmetrically located.
Whilst a soldier has been described being brought into engagement with the
vertical plate 4 it will be readily appreciated that since the plates 5
and 6 are of the same design and each have an associated platform region,
with associated webs 13 exactly the same technique may be utilized to
bring a soldier into engagement with any one of the vertical plates 4, 5,
6 as described above.
The web portions 13 serve to prevent the soldier sliding from side-to-side
relative to the six-way connector before the bolts have been inserted in
position through the apertures 17 in the end plate of the soldier and the
oval apertures formed in the vertical plate of the six-way connector, when
the soldier is in one relative orientation, and serve to support the
soldier with the apertures 17 in alignment with the apertures in the
vertical plate in another relative orientation.
As will later be explained, the end plates of each soldier are generally
rectangular in shape and thus define an elongate axis parallel to the
longer side of the end plate. A reference axis may be associated with each
vertical plate extending from the upper plate through to the lower plate.
In this fashion the relative orientation in which the web portions 13
prevent side-to-side sliding of the soldier may described as having the
elongate axis of the soldier parallel to the reference axis of the
vertical plate. In a like manner, when the reference axis of the vertical
plate is perpendicular to the elongate axis of the soldier, the soldier
will be supported by the web portions 13.
It will be appreciated that the central aperture 6 and the oval apertures 8
formed in the upper plate 2 (and in the lower plate 1) of the six-way
connector have precisely the same relative size and configuration as the
aperture 14 and the oval apertures 15 as described with reference to the
vertical plate 4. It will thus be appreciated that a soldier may be
brought into engagement with the central part of the upper plate 2, and
the central part of the lower plate 1 and may be secured in position by
means of bolts passing through the end plate of the soldier and passing
through the oval apertures 8 formed in the upper plate 2 and the lower
plate 1 of the six-way connector as shown in FIG. 1. The soldiers may be
in either of two relative orientations.
It is to be appreciated that the end plate of each soldier is preferably of
a rectangular form, rather than a square form. Thus each end plate
presents an elongate axis which is parallel with the longer sided of the
end plate. It will also be appreciated that the upper plate and the lower
plate are each also of generally rectangular shape, thus presenting an
elongate axis. The soldiers may be connected to the upper plate or the
lower plate with the elongate axis defined by the end plate of each
soldier parallel with the elongate axis of the upper or lower plate. In an
alternate orientation, the soldiers may be connected to the upper plate or
the lower plate with the elongate axis of the end plate of the soldier
extending transversely or perpendicularly to the axis of the top or bottom
plate.
However, the six-way connector of the present invention is provided with
further apertures formed in the upper plate 2, and the lower plate 1,
these further apertures being provided so that, as shown in FIG. 3, two
soldiers 16 may be connected to the upper plate 2 and two further soldier
16 may be connected to the lower plate 1, with the soldiers being in a
side-by-side parallel relationship. In this case the apertures 17 formed
in the end plate of each soldier will be aligned either with one of the
oval holes 8 or with one of the round holes 9. The central aperture in the
end plate of the soldier will be aligned with the aperture 7.
Whilst FIG. 3 illustrates two soldiers connected to the upper plate 2 and
two soldiers being connected to the lower plate 1 in one relative
orientation it is to be appreciated that the soldiers to be connected to
the upper plate 2 and the lower plate 1 may have an alternative relative
orientation, as illustrated in FIG. 4, whilst still being in a
side-by-side relationship. In this case some of the apertures 17 in the
end plates of the soldiers are aligned with the other one of the two round
apertures 9.
The apertures 6, 7 and 14 are provided so that tie rods may pass completely
through the six-way connector to enable the entire structure to be
tensioned thus increasing the strength of the resultant structure. An
appropriate aperture 18 is also provided at the centre of the cruciform
web 3 for this purpose.
From the description provided above it will be appreciated that the six-way
connector of the invention enables various structures to be fabricated.
The six-way connector is able to receive either one or two soldiers in at
least two directions, thus enabling the strength of the structure to be
selected in accordance with the load carrying capacity required. In all
six directions soldiers can be fixed to the six-way connector in two
different relative orientations. This provides a great degree of
flexibility when designing a structure to be fabricated from soldiers and
six-way connectors. Where each soldier joins the connector, regardless of
the orientation of the soldier and regardless of the number of soldiers
connected to the connector in any one direction, an aperture is provided
to allow a tie rod passing through the soldier to pass also through the
six-way connector. Finally the bottom plate of the connector is extended
to provide means to support each horizontal soldier whilst it is being
connected to the six-way connector, thus making assembly easier. Each
platform is associated with vertical webs which serve to prevent the
soldier from moving from side-to-side when the soldier is in one relative
position, and which support the soldier when the soldier is in the other
relative position, so that the central axis of the soldier is still
aligned with the central aperture formed through the vertical plate.
Whilst the six-way connector has been described in the orientation in which
it will normally be used, the connector may be used in other orientations
if desired.
Whilst the invention has been described, by way of example, with reference
to preferred embodiments thereof it is to be appreciated that many
modifications may be effected to the invention without departing from the
scope of the invention as defined by the following Claims.
